_8 WARNING
-Read and follow the warnings in
~ page 198, Working in the engine com­
partment before opening the hood and
checking the brake fluid level.
- If the brake system indicator light does not
turn off or it turns on while driving, the brake fluid level in the reservoir is too low,
and this increases the risk of an accident.
Stop the vehicle and do not continue driv­
ing. See an authorized Audi dealer or au­
thorized Audi Service Facility for assistance.
- If the brake system indicator light turns on
together with the ABS and ESC indicator
lights, the ABS/ESC regulating function may
be malfunctioning. Functions that stabilize
the vehicle are no longer available. This
could cause the vehicle to swerve, which in­
creases the risk that the vehicle will slide.
Do not continue driving. See an authorized
Audi dealer or authorized Audi Service Facili­
ty for assistance.

Check ing and F illing
Checking and Filling
Gasoline
Fuel supply
Applies to: vehicles with gaso line engine
Using the right fuel helps keep the environment
clean and prevents engine damage.
F u el r eco mmend ati on
The fuel recommended for your vehicle is unle ad­
e d pr em ium
grade gasoline . Audi recommends
using TOP TIER Detergent Gasoline with a mini­
mum octane rating of 91 AKI (95 RON). For more
information on TOP TIER Detergent Gasoline,
p lease go to the offic ial website
(www.toptiergas .com).
The recommended gasoline octane rating for
your engine can also be found on a label located on the ins ide of the fuel filler flap . This rating
may be specified as AK I or RON .
Your veh icle may also be operated using unlead­
ed regular gasoline with a minimum octane rat ­
ing of 87 AKl/91 RON. However, using 87 AKI/91
RON octane fuel w il l slightly reduce engine pe r­
forma nce.
Us e un leade d gaso lin e onl y. Unleaded gasoline
is availab le throughout the USA , Canada, and in
most European countries . We recommend that
you do not ta ke your vehicle to areas or co unt ries
where un leaded gaso line may not be availab le.
For more information on refueling your vehicle,
see
¢page 192.
Octan e rating
Octane rating indicates a gasoline's ability to re­
sist engine damaging "knock" caused by prema­
ture ignit ion and detonation . Therefore, buy ing
the correct grade of gasoline is very important to
he lp prevent poss ible engine damage and a loss
of eng ine performance.
Gasoline most commonly used in the Un ited
States and Canada has the following octane rat­
i n gs that ca n usually be found on the filler pump:
- Premium Grade: 91 - 96 AKI
190
- Regu la r Grade: 87 - 90 AK I
Explanation of the abbreviations:
AKI = Anti Knock Index = (R +M)/2 = (RON +MON)/
2
RON = Research Octane Number
MON = Motor Octane Number.
{[) Note
-Do not use a ny fue l w ith o ctane ratings low­
er than 87 AKI or 91 RON othe rw ise expen­
sive engine damage wi ll occur .
- Do
not use leaded gasoline. The use of lead­
ed gasoline will severely damage your vehi­
cle's catalyt ic converter and its ability to
control exhaust emissions .
Blended gasoline
Applies to: vehicles with gasoline engine
Use of gaso lin e conta ining alcoho l or MTBE
(meth yl tertia ry butyl ether )
You may use unleaded gasoline blended with al­
cohol or MTB E (commonly referred to as oxygen ­
ates) if the blended m ixture meets the follow ing
criteria:
Blend of g asoline methanol (wood alcohol o r
m eth yl alcoho l)
-Anti -knock index must be 87 AKI or h igher.
- Blend must contain no more than 3% metha-
nol.
- Blend must contain more than 2% co -solvents.
Blend of ga soline and ethanol (grain alcohol or
ethyl alc ohol )

General information
Appl ies to: vehicles with selective catalytic reduct ion
In vehicles with selective catalyt ic reduction, a
u rea solution (AdBlue/DEF) is injected into the
exhaust system before a nitrogen oxide catalytic
conve rter to reduce nitrogen em issions . The urea
solution is known as Ad Blue or D EF (Diesel Ex­
haust Fluid) . Ad Blue is used in the follow ing .
The Ad Blue is carried in a separate tank in the ve­ hicle. The AdBlue usage acco unts for approxi ­
mately 0 .5% to 2 .5% of the diese l fuel that is
u sed .

Checking and Filling
& WARNING
AdBlue can irritate the skin, eyes and respira­tory system. If there is contact with the fluid,
flush immediately with plenty of water . Con­
sult a physician if necessary.
(D Note
- Only use Ad Blue that conforms to the
standard ISO 22241 -1. Do not mix any addi ­
tives with the Ad Blue and do not dilute it
with water.
- Do not add Ad Blue to the diesel tank or add diesel fuel to the Ad Blue tank. Do not start
the engine under any circumstances if the
wrong fuel is filled in the tank. There is a
risk of damaging the fuel tank system and
the engine. See an authorized Audi dealer or
authorized Audi Service Facility for assis­
tance.
- AdBlue attacks surfaces such as painted ve­
hicle components, plastic and carpet. Re­
move the fluid as quickly as possible with a
damp cloth and plenty of cold water. If the
Ad Blue has already crystallized, use warm
water and a sponge . AdBlue residue that is
not removed will crystallize and can damage
the affected surface.
- Do not store refill bottles or canisters per ­
manently in the vehicle. If the container
leaks, the escaping AdBlue could damage
the vehicle interior.
- Do not allow AdBlue to come into contact
with clothing. If there is contact with the
fluid , flush immediately with plenty of
wa­
ter.

Check ing and F illing
- Do not drive until the fuel tank becomes
complete ly empty . The engine cou ld mis­
fire . Unburned fuel could also get into the
exhaust system and this cou ld cause the
catalytic converter to overheat.
- Do not sw itch off the ignition while the vehi­
cle is moving .
- Do not continue to operate your vehicle un­
der these cond itions, as otherwise fuel can
reach the catalytic converter . This could re­
su lt in overheating of the converter, requ ir­
i ng its replacement .
- To assure efficient operation of the Emis­
sion Control System :
- Have your ve hicle main tained pro perly and
in accordance with the service recommen ­
dations in your Wa rranty & Maintenance
book let.
- Lac k of proper maintenance as well as im ­
proper use of the vehicle will impair the
function of the emission cont rol system
and could lead to damage.
@ For the sake of the environment
Even when the Emission Control System is op­
erat ing properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erat ing states . This depends on the su lfur
content of the fuel be ing used . Using a differ­
ent brand of fue l may he lp, or filling the tan k
w ith lead-free super grade gasoline.
